Though some of the sheep may wander, the eye of the Shepherd is upon them, and sooner or later they will feel the tentacles of Divine Providence reaching out after them and drawing them back to the fold.

Either in this life or in the life to come, they will return. They will have to pay their debt to justice; they will suffer for their sins; and may tread a thorny path; but if it leads them at last, like the penitent Prodigal, to a loving and forgiving father's heart and home, the painful experience will not have been in vain.

- the Prophet Joseph Smith

Again, our existence in the spirit world is part of the mortal sector of our Fatherís plan which culminates with the Judgment and the Resurrection.
